Diamond Learning, Reimagined.
Diamonds are more than grades—they’re light, structure, and brilliance. As the trade shifts from physical counters to virtual screens, the way we learn must evolve too. The 4Cs remain the foundation of diamond grading. CDA's Visual Interpretation (VI) framework builds upon that foundation through SLPES™—a universal methodology for evaluating any diamond, regardless of shape, cutting style, grading report, or era. By focusing on visual performance rather than specifications alone, SLPES™ teaches a consistent way to observe, interpret, and evaluate every diamond.
Every diamond. Every shape. Every era. One framework. SLPES™.
